Different scuba gear types weigh different amounts. The oxygen tank is the heavy part of the scuba diving gear.
No practical SCUBA gear existed until it was developed by Jacques Cousteau in the 1940's, improving on his aqua-lung design. da Vince was farsighted and speculated about many things, but he did not build usable underwater breathing gear.

Scuba gear
Modern SCUBA gear was developed in the mid-20th century, with significant contributions from inventors like Jacques Cousteau and Emile Gagnan, who created the Aqua-Lung. This equipment allows divers to breathe compressed air while submerged, enabling them to explore greater depths safely and for extended periods. The gear includes a tank for storing air, a regulator to control airflow, and a buoyancy control device, enhancing both safety and comfort underwater. Overall, SCUBA gear revolutionized underwater exploration and recreational diving.
Many scuba stores sell scuba diving cameras. Check a scuba gear stores in your area. This will allow you to compare cameras and get advise from fellow scuba divers.
The best area to sell scuba gear in the USA is to set up scuba gear shops in areas near bays and oceans. This could mean on the USA's three major coastlines and also the many large lakes that exist in so many places in the US. The Great Lakes is an excellent place to sell scuba gear.
